クマを念頭に置いて、親フォームまたは何もしませんJSリスナーなしで入力を提出します。だから、最も簡単な方法は、例えば、アクションとして自分のページ名を持つ<form>を作ることになります。

<form action="<?echo $PAGE_NAME?>" method="POST" > 
    <table class="table" align="center"> 
    <tr> 
     <thead> 
      <td>year</td> 
      <td>Area at the starting year</td> 
      <td>Maximum profit per hectare</td> 
      <td>Minimum profit per hectare</td> 
      <td>Area at the ending year</td> 
      <td>Area in hectare</td> 
      <td></td> 
     </thead> 
    </tr> 

    <tr> 
     <td>2011-2012</td> 
     <td><input type="number" id="areas12" name="areas12"></td>

     <td><input type="number" id="volume12" name="volume12"></td> 
     <td> 
      <button type="submit" class="btn btn-primary btn btn-block">Save</button>
